Apple 2 Soft Switch
Inspired by Anthony's program over in c.s.a2 here is a Applesoft BASIC program to display a memory map and limited soft switches.
- ESC = exit
- SPC = toggle status lines to show description / soft-switch addresss
NOTE: The IO soft switch address don't exactly match the hardware switches due to:
a) some are contiguous b) some require multiple locations to activate (i.e. TEXT/GR and Lo-Res/Hi-Res)
RW columns gives us a little more space on the right. Here is a mock-up:
v4 ___READ___ __WRITE___ $FFFF| ROM | ROM | C088 BANK2 $E000|__________|__________| /C081 HRAMWRT | ROM | ROM | / C080 HRAMRD $D000|__________|__________|/ C057 HIRES :__________:__________: C055 PAGE2 $BFFF| AUX | AUX |\ C008 ALTZP $6000|__________|__________| \ C004 RAMWRT | AUX | AUX | \C002 RAMRD $4000|__________|__________| C000 80STORE
- Version number now shown in top left
- Fixed 80STORE=1 display for HGR1 and TEXT1
- Removed most odd addresses in the main 48 KB as they were cluttering up the display too much.
